Well, obviously. Ra is among the earliest, most fleshed out solar deities. He faces the underworld every night, and brings light to the world at daybreak. Not only does he share many of Superman's powers — flight, powerful sight, and super-strength — he is the freaking sun. Literally speaking, he is a ball of gas 300,000 times the size of Earth, and his radiance happens to be what makes Superman tick in the first place. Enjoy the sunset, Superman. It's going to be your last.
